In time, bronze became the primary material for tools and weapons, and a good part of the stone technology became obsolete, signaling the end of the Stone Age.We're a small non-profit organisation run by a handful of volunteers.Tools and weapons during the Stone Age were not made exclusively of stone: organic materials such as antler, bone, fibre, leather and wood were also employed.The archaeological record, however, is biased in favour of items made of stone because these are far more durable than the organic materials, which are easily obliterated by the many processes of decay that they are subject to and can only survive under rare circumstances such as cold temperatures or very dry climate.During the Early Neolithic era, around 8,000 BCE, special ovens used to parch cereal grains and to bake bread were being built in the Near East, which allowed people to control fire and produce high temperatures in enclosed facilities.

In fact, the earliest tools pre-date the emergence of the Homo genus, and it is believed that some of the Australopithecines were the first tool makers.Other durable materials such as copper and glass-made items have also survived.Under rare circumstances, plant, animal, and human remains have also managed to survive, sometimes merely fossilized, but other times they still present part of the soft tissue such as the several frozen specimens of the extinct woolly rhino and woolly mammoth that have survived in Siberia virtually intact.This “Three Age System” has received some criticism.There are scholars who believe that this approach is too technologically oriented.

The reason is that the capacity of tool use and even its manufacture is not exclusive of our species: there are studies indicating that bonobos are capable of flaking and using stone tools in order to gain access to food in an experimental setting.
